SPECIFICATION forming para; oflLetters Patent 110,276,272, dated April 24, 188e, Application filed September 4, 1882. (No model.)

To all whom it may concern Be itknown that I, WILLIAM H. PARLIN, residing at Canton, in the county ot' Fulton and State of1llinois,and acitizen ofthe United States, have invented a new and useful Improvement in Cultivators, ot' which the following is a full description, reference being had to the accompanying drawings, in which` Figure l is a rear elevation, the plow-beams being shown in section. Fig. 2 isa side elevation, one wheel being removed. Fig. 3 is a detail, being a plan of one plow-beam and a device connected therewith, by means of which, when desired,"the plows can be supported free from the ground. Figs-,4 and `5 are details, Fig. 5 being a section at line .fr ot Fig. 4. Fig. 6 is a plan of the `parts represented. Figs. 7 and 8 show a modification. It is common to connect the two gangs of plows in a cultivator with each other by means of an arched bar, and tofhinge the wheels to the ends ot' such bar. Heretofore it has been usually thought important to so construct cultivators that the wheels would be kept in the line of progression when one beam was advanced a little forward ot the other or when the plow-beams were moved laterally. I think it desirable tohave a cnltivator so constructed that "when eithergang of plows is moved laterally the wheel will also be moved out ot' the line of progression, either to the right or to the left. f i i l A My invention relates, tirst, to devices lby means of which theiwheels are hinged to the `arched bar; second, todevices by meansot which, when theoperator moves either plowbeam laterally, the corresponding-wheel will also be moved a little out of the line ot' pro-` gression, either to the right or let't, as the case maybe. i y i 1n the drawings, A represents an arched bar having upon each side a horizontal portion, c, to which the plow-beams are connected, and at each end a downwardextension, b. B is a bracket having ears c at the top and bottom, through which ears the end b ot' the arch passes, thus hinging the bracket upon the end ot the arch. dis a spindle nponwhich the wheel is supported. `It is iirmly secured to the bracket B.- In manufacturin g the spindleand bracket maybe cast. together. From the upper ear, c, ot' the bracket B there is a forward extension or bar, e.

O is adrat't-bar hinged upon the end bof the arch.

l) is a sleeve upon the end b ofthe arch,be tween the earc and the socket ot' the draft-bar O. Ot course the draft-bar C and the sleeve D may be cast together.

E is a bar pivotally connected at its forward end,f, with the draft-bar C, or, as shown,to alittle projection upon such draft-bar. At the center of this bar E is a short slot,g, through which passes a bolt, h, the lower end of which is secured in the forward end of the extension e, the ear c being held loosely at this point in connection with the forward end of the extension e, so that such bar E can turnupon the bolt h.V

F is a small bent rod, one end ot' which is rigidly secured, as shown, to one end of a small plate, t, while the other end ot' this plate is pivotally connected with the rear end ot' the bar E. The plate i may be omitted, one end ot the rod Fbeingpivotally connected directly with the rear end of the plate E. The other end of this rod F passes through a loop or eye, j, upon the side ot' the plow-beam.

` Gr G are the plow-beams, hinged in a suitable manner upon the horizontal part a or" the arched bar A, so that the plow-beams can have either a vertical or lateral movement.

i' The operation of this part of my invention is as follows: The machine is designed to cultivate both sides ot`a row ofplants at the same time,`and to be drawn by two animals,one of which is hitched to each of the drat'tbars O. The wheels, being pivoted upon thelower ends ot" the arch, are each free to be turned out o' the direct line ot' progression, and it the operator movesthe rear end ot' the plow-beam G toward its wheel that partot' the wheel which is forward of the spindle will be turned outward and out the line ot' progressiombecause the'rear end ofthe bar e will by the action ot' the bent rod F be thrown a` little toward the wheel, and this movement of this bar E will move the forward end of the extension e a little toward the wheel, because the bar E is pivoted at its'forward end to the draftbar C and near its center to thepextcnsion c, andas this extension c is connected with the bracket B its ISO movement either to the right or left causes the bracket to spring or turn upon the part b of the arch, and. the wheel-spindle being permanently connected with the bracket B, the wheel must alsobe turned by the movement of the bracket B If this beam Gr be moved in the opposite direction, away from the wheel, the forward part of the wheel will in the same manner be thrown inward alittle and out of the line of progression. The operation as to the other beam is precisely the same as that already described. It' the two plow-beams were connected together at their rear ends, then when they were moved laterally both wheels would be thrown out of the line of progression at the same time, one being thrown outward and the other one inward. The draft ofthe animals maintains the draft-bar G in the line of progression. This construction, which causes the wheels to be moved out of the line of progression when the plow-beams are moved laterally, is desirable, because the operator has more perfect control of the eultivator, and, in dodging plants, is aided by the action of the wheels. It frequently happens in use that the cultivator gets out of line, the center of the machine being carried to one side of the center line, especially on side hills or where one of the horses is inclined to crowd. Then the operator, by turning the wheels a little, can quickly bring the cultivator to the proper place. This construction can be used with cultivators which have a tongue; but it -is more desirable with the tongueless cultivator. With this construction the wheels are controlled by the operator and not by the animals.

In Figs. 7 and S I have shown a modification or" this feature, by which I dispense with the bar E and make a direct connection between the plow-beam and the extension c by means of an angular rod havingl two arms, l and m, the rear end of l passing through an eye, n, upon the plow-beam, and the end of the arm m passing down into a hole in the extension c. The other end of m is extended beyond the point of connection with l, and passes loosely through a hole in a brace or support, o, which is connected with the arched bar A at one end and with the draft-bar C at the other end. Some other support for this end of the rod m might be used. p is simply a brace connecting Zand m. With this construction, if the rear end ot' the plow-beam be moved either to the right or to the left, the extension c from the bracket B will also be moved either to the right or to the left, carrying with it the wheel, as before, the rod m sliding in its support o. Thus the operation with this modification is precisely the same as before, the difference in construction being that the connection between the plow-beam and the extension e is made in a somewhat different manne-r than before described.

"'His abar hinged near its forward end to one side of one of the plow-beams. Near the forward end of this bar H is a lateral projection or lflange, lr, which, as shown in Fig. 3, extends over the beam. Thisl projection k is notched at its forward end, and the lip 7c is curved downward slightly. The outer end, o', of the bar H is enlarged and bent.

The operation of this part ofmy invention is as follows: When the bar His not in use it can be supported by the side of the plowbeam by means ofthe flange 7c, which rests upon the beam, and the lip k will prevent the flange 7c from slipping off from the beam. By lifting up the rear end of the bar H the lip will be carried up above the beam, and then the bar H can be moved over a little away from the beam, and then can be brought down to the ground, and at the same time, if the beam be lifted a little, it can be made to enter the notch at the forward end of the dan ge k, and thus, the bar H being of suitable length, the plows will be supported free from the ground, the outer or lower end, r, of the barH resting on the ground. The position of this bar and of the plow-beam, when theplows are out of the ground, is shown by dotted lines in Fig. 2.

I have shown and described the part e as an extension from the bracket B and integral therewith. This part might be aseparate arm or bar secured to the bracket; but the irst form is the best.

Instead of placing the notched ange or plate 7s upon the bar H, a notched flange or plate might be secured to and project from the plowbeam, such notched flange being arranged so as to receive and hold the bar H by the side of the beam, and also so arranged that the notch will engage with the bar H when the bar is down for the purpose of supporting the beam in an elevated position.

I am aware that it is not new to swivel the wheel-support of a cultivator and connect such ICO support with the plow-beam in such manner y that lateral movements of the beam impart corresponding movements to the wheel; but such is not broadly claimed by me.

What I cla-im as new, and desire to secure by Letters Patent, is as follows:

1. In a cultivator, the combination, with an arch or frame, A, having a horizontal portion, a, and vertical portion b, and aplow-beam, G, pivotal] y connected with the portion a to move laterally, of the wheel-carryin g bracket B, pivoted to the said vertical portion b, and provided at its upper end with a forward extension, e, and a connection between the forward extension and the plow-beam,whcrebylateral movements of the latter will swing the bracket on the vertical portion of the arch or frame, substantially as described.

2. In acultivator, the combination ofan arch or frame having the vertical portion b, and a plow-beam pivotally connected with the arch or frame to move laterally, with the wheel-carrying bracket B, having top and bottom ears, c, pivoted on the said vertical portion b, the upper ear having a forward extension, e, andthe rro B, provided with the forward extension, c, of

i connected at or near the center of its length with the forward extension, and the rod F, cont sion and the plow-beam, whereby lateral moveconnecting devicesbetween the forward extenments of the latter will swing the wheel-carrying bracket on the vertical portion of the arch or frame,substantall y as and for the pur` poses described.

3. In a cultivator, the combinatiomwith the arch or frame A, the plow-beam G, pi'votally connected therewith to permit itslateralniove-- ment, and the pivoted wheel-carrying bracketthe bar E, pivoted at its forward portion, und

necting the rear end of the said bar with the plow-beam, substantially as and for the purpose described. Y

4. In Va cnltivator, the combination of an arched bar, A, bracket B, hinged to the end b hof the archedbar and provided with a wheela lateral movement is given to the plow-beam the Wheel will be thrown out of the line of'progression, substantially as specified.
